Laser soldering Answered

So im making a  laser spirograph (https://www.instructables.com/id/Laser-Spirograph/#step1) and i just got my laser diode to come out of its case, and i was wondering where i should solder the red and black wire as it does not look like the one in the 'ible. the laser diode looks like this one here http://10mW 532nm Green Laser Module (3V 11.9mm)  (i would take a pic of the diode but i cant find my camera!) the only difference in the diodes is that mine has a black button instead of the red. Oh and one more thing is that it has to bypass the use of the button. Thanks in advance!!!!!!!!
